LESSON LEARNED: If you take a Valkyrie out for coffee, you’ll get stuck with the check and a dead body.

I hadn’t seen Samirah al-Abbas in almost six weeks, so when she called out of the blue and said we needed to talk about a matter of life and death, I agreed right away. (Technically I’m already dead, which means the whole life-and-death thing didn’t apply, but still…Sam sounded anxious.)

She hadn’t yet arrived when I got to the Thinking Cup on Newbury Street. The place was packed as usual, so I queued up for cof- fee. A few seconds later, Sam flew in—liter- ally—right over the heads of the café patrons.

Nobody batted an eye. Regular mortals aren’t good at processing magical stuff, which is fortunate, because otherwise Bosto- nians would spend most of their time run- ning around in a panic from giants, trolls, ogres, and einherjar with battle-axes and lattes.

Sam landed next to me in her school uni- form—white sneakers, khaki slacks, and a long-sleeve navy shirt with the King Academy logo. A green hijab covered her hair. An ax hung from her belt. I was pretty sure the ax wasn’t standard dress code.

As glad as I was to see her, I noted that 14/876

the skin under her eyes was darker than usu- al. She was swaying on her feet. “Hey,” I said. “You look terrible.” “Nice to see you, too, Magnus.” “No, I mean…not terrible like different than normal terrible. Just terrible like exhausted.”

“Should I get you a shovel so you can dig that hole a little deeper?”

I raised my hands in surrender. “Where have you been the last month and a half?”

Her shoulders tightened. “My workload this semester has been killing me. I’m tutor- ing kids after school. Then, as you might re- member, there’s my part-time job reaping souls of the dead and running top secret mis- sions for Odin.”

“You kids today and your busy schedules.”

“On top of all that…there’s flight school.”

Flight school?” We shuffled forward with

the line. “Like airplanes?”

I knew Sam’s goal was to become a pro- fessional pilot someday, but I hadn’t realized she was already taking lessons. “You can do that at sixteen?”

Her eyes sparkled with excitement. “My grandparents could never have afforded it, but the Fadlans have this friend who runs a flight school. They finally convinced Jid and Bibi—”

“Ah.” I grinned. “So the lessons were a gift from Amir.”

Sam blushed. She’s the only teenager I know who has a betrothed, and it’s cute how flustered she gets when she talks about Amir Fadlan.

“Those lessons were the most thoughtful, the most considerate…” She sighed wistfully. “But enough of that. I didn’t bring you here to talk about my schedule. We have an in- formant to meet.”

“An informant?”

16/876

“This could be the break I’ve been waiting for. If his information is good—”

Sam’s phone buzzed. She fished it out of her pocket, checked the screen, and cursed. “I have to go.”

“You just got here.”

“Valkyrie business. Possible code three- eight-one: heroic death in progress.” “You’re making that up.” “I’m not.”

“So…what, somebody thinks they’re about to die and they text you ‘Going down! Need Valkyrie ASAP!’ followed by a bunch of sad-face emojis?”

“I seem to recall taking your soul to Val- halla. You didn’t text me.” “No, but I’m special.” “Just get a table outside,” she said. “Meet my informant. I’ll be back as soon as I can.”

“I don’t even know what your informant looks like.” “You’ll recognize him when you see him,”

Sam promised. “Be brave. Also, get me a scone.”

She flew out of the shop like Super Muslima, leaving me to pay for our order.

I got two large coffees and two scones and found a table outside.

Spring had arrived early in Boston. Patches of dirty snow still clung to the curbs like dental plaque, but the cherry trees popped with white and red buds. Flowery pastel clothing displays bloomed in the win- dows of high-end boutiques. Tourists strolled by enjoying the sunshine.

Sitting outside, comfortable in my freshly laundered jeans, T-shirt, and denim jacket, I realized this would be the first spring in three years that I hadn’t been homeless.

Last March, I had been scrounging from Dumpsters. I’d been sleeping under a bridge in the Public Garden, hanging out with my buddies Hearth and Blitz, avoiding the cops

and just trying to stay alive.

Then, two months ago, I died fighting a fire giant. I’d woken up in the Hotel Valhalla as one of Odin’s einherji warriors.

Now I had clean clothes. I took a shower every day. I slept in a comfortable bed every night. I could sit at this café table, eating food I’d actually paid for, and not worry about when the staff would force me to move along.

Since my rebirth, I’d gotten used to a lot of weird stuff. I’d traveled the Nine Worlds meeting Norse gods, elves, dwarves, and a bunch of monsters with names I couldn’t pronounce. I’d scored a magical sword that presently hung around my neck in the form of a runestone pendant. I’d even had a mind- melting conversation with my cousin Anna- beth about the Greek gods who hung out in New York and madeher life difficult.

Apparently North America was lousy with 19/876

ancient gods. We had a full-blown infestation.

All of that I’d learned to accept.

But being back in Boston on a nice spring day, hanging out like a regular mortal kid? That felt strange.

I scanned the crowd of pedestrians, look- ing for Sam’s informant. You’ll recognize him when you see him, she’d promised. I wondered what kind of information this guy had, and why Sam considered it life-and- death.

My gaze fixed on a storefront at the end of the block. Over the doorway, the brass- and-silver sign still gleamed proudly: BLITZEN’S BEST, but the shop was shuttered. The front door window was papered over on the inside, with a message hastily scrawled in red marker: Closed for remodeling. Back soon!

I’d been hoping to ask Samirah about that. I had no idea why my old friend Blitz had abruptly disappeared. One day a few weeks ago, I’d just walked by the shop and found it closed. Since then, there’d been no word from Blitzen or Hearthstone, which wasn’t like them.

Thinking about this made me so preoccu- pied I almost didn’t see our informant until he was right on top of me. But Sam was cor- rect: he kind of stood out. It’s not every day you see a goat in a trench coat.

A porkpie hat was wedged between his curly horns. A pair of sunglasses perched on his nose. His trench coat kept getting tangled in his back hooves.

Despite his clever disguise, I recognized him. I’d killed and eaten this particular goat on another world, which is the sort of bond- ing experience you don’t forget. “Otis,” I said.

“Shhh,” he said. “I’m incognito. Call me…Otis.”

21/876

“I’m not sure that’s how incognito works, but okay.”

Otis, aka Otis, climbed into the chair I’d reserved for Sam. He sat on his back haunches and put his front hooves on the table. “Where is the Valkyrie? Is she incog- nito, too?” He peered at the nearest pastry bag as if Sam might be hiding inside.

“Samirah had to go reap a soul,” I said. “She’ll be back soon.”

“It must be nice having a purpose in life.” Otis sighed. “Well, thank you for the food.” “That’s not for—”

Otis snapped up Sam’s scone bag and began to eat it, paper and all.

At the table next to us, an older couple glanced at my goat friend and smiled. Maybe their mortal senses perceived him as a cute child or a funny pet dog

I flashed back to January, when I’d first 23/876

met the thunder god. Good times around the campfire, listening to Thor fart, talk about his favorite TV shows, fart, complain about his missing hammer, which he used to kill gi- ants and stream his favorite TV shows, and fart.“It’s still missing?” I asked.

Otis clacked his front hooves on the tab- letop. “Well, not officially, of course. If the giants knew for certain that Thor was without his you-know-what, they would in- vade the mortal worlds, destroy everything, and send me into a very deep funk. But unof- ficially…yes. We’ve been searching for months with no luck. Thor’s enemies are get- ting bolder. They sense weakness. I told my therapist it reminds me of when I was a kid in the goat pen and the bullies were sizing me up.” Otis got a faraway look in his yellow slit-pupil eyes. “I think that’s when my trau- matic stress started. This was my cue to spend the next several

hours talking to Otis about his feelings. Be- ing a terrible person, I just said “I feel your pain” and moved on.

“Otis,” I said, “the last time we saw you, we found Thor a nice iron staff to use as a backup weapon. He’s not exactly defenseless.”

“No, but the staff is not as good as the…ham. It doesn’t inspire the same fear in the giants. Also, Thor gets cranky trying to watch his shows on the staff. The screen is tiny, and the resolution is terrible. I don’t like it when Thor is cranky. It makes it hard for me to find my happy space.”

A lot about this did not make sense: why Thor would have so much trouble locating his own hammer; how he could possibly have kept its loss a secret from the giants for so long; and the idea that Otis the goat would have a happy space.

“So Thor wants our help,” I guessed. “Not officially.”

“Of course not. We’ll all have to wear trench coats and glasses.”

25/876

“That’s an excellent idea,” Otis said. “Anyway, I told the Valkyrie I would keep her updated since she is in charge of Od- in’s…you know, special missions. This is the first good lead I’ve gotten to the location of the certain object. My source is reliable. He’s another goat who goes to the same psychiat- rist. He overheard some talk in his barnyard.”

“You want us to track down a lead based on barnyard gossip you heard in your psychi- atrist’s waiting room.”

“That would be great.” Otis leaned so far forward I was afraid he might fall out of his chair. “But you’re going to have to be careful.”

It took all my effort not to laugh. I’d played catch-the-lava-ball with fire giants. I’d eagle-skied over the rooftops of Boston.

I’d pulled the World Serpent out of Mas- sachusetts Bay and defeated Fenris Wolf with a ball of yarn. Now this goat was telling me to be careful.

“So where is the ham?” I asked. “Jotun- heim? Niflheim? Thorfartheim?”

“You’re teasing.” Otis’s sunglasses slipped sideways on his snout. “But the ham is in a different dangerous location. It’s in Provincetown.”

“Provincetown,” I repeated. “On the tip of Cape Cod.”

I had vague memories of the place. My mom had taken me there for a weekend one summer when I was about eight. I re- membered beaches, saltwater taffy, lobster rolls, and a bunch of art galleries. The most dangerous thing we’d encountered was a seagull with irritable bowel syndrome.

Otis lowered his voice. “There is a barrow in Provincetown—a wight’s barrow.” “Is that like a wheelbarrow?

wants us to have a chance to be heroes. Or 28/876

it’s hard work and he has some shows to catch up on.”

“To be fair,” Otis said, “the new season of Jessica Jones did just start streaming.”

It’s not the goat’s fault, I told myself. He does not deserve to be punched.

“Fine,” I said. “When Sam gets here, we’ll talk strategy.”

“I’m not sure I should wait with you.” Ot- is licked a crumb off his lapel. “I should have mentioned this earlier, but you see, someone…or something…has been stalking me.”The hairs on my neck tingled. “You think

they followed you here?”

“I’m not sure,” Otis said. “Hopefully my disguise threw them off.” Oh, great, I thought. I scanned the street but saw no obvious lurkers. “Did you get a good look at this someone/something?”

noticing that Otis was not a cute puppy dog.

He was, in fact, a dead goat.

I scanned the rooftops across the street. Judging from the angle of the ax, it must have been thrown from somewhere up there…yes. I caught a flicker of movement just as the attacker ducked out of sight—a figure in black wearing some sort of metal helmet.

So much for a leisurely cup of coffee. I yanked the magical pendant from my neck chain and raced after the goat-assassin.

I SHOULD introduce my sword.

Jack, these are the peeps. Peeps, this is Jack.His real name is Sumarbrander, the

Sword of Summer, but Jack prefers Jack be- cause reasons. When Jack feels like snooz- ing, which is most of the time, he hangs out on a chain around my neck in the form of a 32/876 pendant marked with fehu, the rune of Frey:

When I need his help, he turns into a sword and kills things. Sometimes he does this while I wield him. Other times he does this while flying around on his own and singing annoying pop songs. He is magical that way.

As I bounded across Newbury Street, Jack sprang to full form in my hand. His blade—thirty inches of double-edged bone- forged steel—was emblazoned with runes that pulsed in different colors when Jack talked.

“What’s going on?” he asked. “Who are we killing?”

Jack claims he doesn’t pay attention to my conversations when he is in pendant form. He says he usually has his headphones

on. I don’t believe this, because Jack doesn’t have headphones. Or ears.

“Chasing assassin,” I blurted out, dodging a taxi. “Killed goat.”

“Right,” Jack said. “Same old, same old, then.”

I leaped up the side of the Pearson Pub- lishing building. I’d spent the last two months learning to use my einherji powers, so one jump took me to a ledge three stories above the main entrance—no problem, even with a sword in one hand. Then I hop- climbed from window ledge to cornice up the white marble facade, channeling my inner Hulk until I reached the top.

On the far side of the roof, a dark bipedal shape was just disappearing behind a row of chimneys. The goat-killer looked humanoid, which ruled out goat-on-goat homicide, but I’d seen enough of the Nine Worlds to know that humanoid didn’t mean human. He could be an elf, a dwarf, a small giant, or even an ax-murderer god. (Please, not an ax- murderer god.)

By the time I reached the chimneys, my quarry had jumped to the roof of the next building. That might not sound impressive, but the next building was a brownstone man- sion about fifty feet away across a small parking lot. The goat-killer didn’t even have the decency to break his ankles on impact. He somersaulted on the tar and came up running. Then he leaped back across New- bury Street and landed on the steeple of the Church of the Covenant. “I hate this guy,” I said. “How do you know it’s a guy?” Jack asked.

The sword had a point. (Sorry, I keep stumbling into that pun.) The goat-killer’s loose black clothes and metal war helmet made it impossible to guess his or her gender, but I decided to keep thinking of him as male for now. Not sure why. I guess I found the idea of a bro goat-assassin more annoying.

I backed up, took a running start, and leaped toward the church.

35/876

I’d love to tell you I landed on the steeple, slapped some handcuffs on the killer, and announced, You’re going away for livestock murder!

Instead…well, the Church of the Coven- ant has these beautiful stained glass win- dows made by Tiffany in the 1890s. On the left side of the sanctuary, one window has a big crack at the top. My bad.

I hit the church’s slanted roof and slid back, grabbing the gutter with my right hand. Spikes of pain shot up my fingernails. I dangled from the ledge, my legs flailing, kicking the beautiful stained glass window right in the Baby Jesus.

On the bright side, swinging precariously from the roof saved my life. Just as I twisted, an ax hurtled from above, slicing the buttons

off my denim jacket. A centimeter closer and it would’ve opened up my chest. “Hey!” I yelled.

I tend to complain when people try to kill me. Sure, in Valhalla we einherjar are con- stantly killing each other, and we get resur- rected in time for dinner. But outside Val- halla, I was very much killable. If I died in Boston, I would not be getting a cosmic do- over.The goat-assassin peered down at me

from the peak of the roof. Thank the gods, he appeared to be out of throwing axes. Unfor- tunately, he still had a sword at his side. His leggings and tunic were stitched from black fur. A soot-smeared chain mail coat hung loosely on his chest. His black iron helmet had a chain mail curtain around the base—what we in the Viking business call an aventail—completely covering his neck and throat. His features were obscured by a faceplate fashioned to resemble a snarling 37/876 wolf.Of course a wolf. Everybody in the Nine

Worlds loves wolves. They have wolf shields, wolf helmets, wolf screen savers, wolf paja- mas, and wolf-themed birthday parties. Me, not so much loving the wolves. “Take a hint, Magnus Chase.” The assas- sin’s voice warbled, modulating from sop- rano to baritone as if going through a special effects machine. “Stay away from Provincetown.”

The fingers of my left hand tightened on the hilt of my sword. “Jack, do your thing.” “You sure about that?” Jack asked. The assassin hissed. For some reason, people are often shocked when they find out my sword can talk.

“I mean,” Jack continued, “I know this guy killed Otis, but everybody kills Otis. Get- ting killed is part of Otis’s job description.” “Just chop off his head or something!” I 38/876

yelled.

The assassin, not being an idiot, turned and fled.

“Get him!” I told Jack.

“Why do I have to do all the hard work?” Jack complained.

“Because I’m dangling here and you can’t be killed!”

“Just because you’re right doesn’t make this cool.”

I flung him overhead. Jack spiraled out of view, flying after the goat-killer while singing his own version of “Shake It Off.” (I have never been able to convince him that the line isn’t cheese graters gonna grate, grate, grate, grate, grate.)

Even with my left hand free, it took me a few seconds to haul myself up to the roof. Somewhere to the north, the clanging of blades echoed off brick buildings. I raced in that direction, leaping over the church’s turrets, launching myself across Berkeley Street. I bounced from rooftop to rooftop un- til I heard Jack yell in the distance, “OW!”

Most people might not run into battle to check on the welfare of their swords, but that’s what I did. At the corner of Boylston, I scrambled up the side of a parking garage, got to the roof level, and found Jack fighting for his…well, maybe not his life, but at least his dignity.

Jack often bragged that he was the sharpest blade in the Nine Worlds. He could cut through anything and fight a dozen en- emies at once. I tended to believe him, since I’d personally seen him take out giants the size of skyscrapers. Yet the goat-killer was having no trouble forcing him back across the roof. The assassin might have been small, but he was strong and quick. His dark iron sword sparked against Jack. Every time the two blades connected, Jack yelped, “Ow! Ow!” I didn’t know if Jack was in real danger, 40/876

but I had to help. Since I didn’t have another weapon and I didn’t feel like fighting empty- handed, I ran to the nearest lamppost and ripped it out of the cement.

That sounds like I was showing off. Hon- estly, I wasn’t. The pole was just the handiest weapon-like object I could find—except for a parked Lexus, and I wasn’t quite strong enough to wield a luxury automobile.

I charged the goat-killer with my twenty- foot-long jousting light fixture. That got his attention. As he turned toward me, Jack lashed out, opening a deep cut in the assas- sin’s thigh. The goat-killer grunted and stumbled.

That was my chance. I could have taken him down. Instead, when I was ten feet away, a distant howl cut through the air and froze me in my tracks.

Jeez, Magnus, you’re thinking, it was only a distant howl. What’s the big deal? I may have mentioned I don’t like wolves.

When I was fourteen, two of them with glow- ing blue eyes killed my mother. My recent encounter with Fenris hadn’t done anything to increase my appreciation for the species.

This particular howl was definitely that of a wolf. It came from somewhere across the Boston Common, reverberating off the high- rises, turning my blood to Freon. It was ex- actly the same sound I’d heard the night of my mother’s death—hungry and triumphant, the baying of a monster that had found its prey.The lamppost slipped from my grip,

clanging against the asphalt.

Jack floated to my side. “Uh, señor…are we still fighting this guy or what?”

The assassin staggered backward. The black fur of his leggings glistened with blood. “And so it begins.” His voice sounded even more garbled. “Beware, Magnus. If you go to Provincetown, you will play into your en- emy’s hands.”

42/876

I stared at that snarling face mask. I felt like I was fourteen again, alone in the alley behind my apartment the night my mother died. I remembered gazing up at the fire es- cape from which I had just dropped, hearing the wolves howl from our living room. Then flames exploded from the windows. “Who—who are you?” I managed. The assassin let out a guttural laugh. “Wrong question. The right question: Are you prepared to lose your friends? If not, you should leave Thor’s hammer lost.”

He backed to the edge of the roof and toppled over.

I ran to the ledge just as a flock of pigeons surged upward, rising in a blue-gray cloud, swirling away over the Back Bay’s forest of chimneys. Down below: no movement, no body, no sign of the assassin. Jack hovered next to me. “I’ve could’ve 43/876

taken him. You just caught me unprepared. I didn’t have time to do my stretches.” “Swords don’t stretch,” I said. “Oh, excuse me, Mr. Expert on Proper Warm-up Techniques!”

A tuft of pigeon down helicoptered to the ledge and stuck in a smear of the assassin’s blood. I picked up the tiny feather and watched red liquid soak into it.

“So what now?” Jack asked. “And what was that wolf howl?”

Ice water trickled down my eustachian tubes, leaving a cold, bitter taste in my mouth. “I don’t know,” I said. “Whatever it was, it’s stopped now.”

“Should we go check it out?”

“No! I mean…by the time we figured out where the sound came from, we’d be too late to do anything about it. Besides…”

I studied the bloody pigeon feather. I wondered how the goat-killer had disappeared so effectively, and what he knew

about Thor’s missing hammer. His distorted voice reverberated in my mind: Are you pre- pared to lose your friends?

Something about the assassin had seemed very wrong…yet very familiar.

“We have to get back to Sam.” I grabbed Jack’s hilt and exhaustion washed over me.

The downside of having a sword who fights on his own: whatever Jack did, I paid the price as soon as he returned to my hand. I felt bruises spreading across my arms—one for each time Jack had been struck by the other sword. My legs trembled like they’d been doing lunges all morning. A lump of emotion formed in my throat—Jack’s shame for letting the goat-killer fight him to a standstill.

“Hey, man,” I told him, “at least you cut him. That’s more than I did.”

“Yeah, well…” Jack sounded embar- rassed. I knew he didn’t like sharing the bad stuff with me. “Maybe you should rest for a 45/876

minute, señor. You’re in no shape—”

“I’m all right,” I said. “Thanks, Jack. You did good.”

I willed him to return to pendant form, then reattached the runestone to my neck chain.

Jack was right about one thing: I needed rest. I felt like crawling inside that nice Lexus and taking a nap, but if the goat-assassin de- cided to double back to the Thinking Cup, if he caught Sam unaware…

I took off across the rooftops, hoping I wasn’t too late.
